All new for 2013 Connelly Sonic is the ski built for FUN on the water! Connelly threw the tool box at this one with everything that they have learned, proven, and perfected over the forty eight years of Connelly Skis. The side-cut is wide in the tip and narrow in the tail. Connelly added Hook grooves on each side of the tunnel, 6 V-shaped steps for a less drag on the water and the most forgiving flex pattern ever created. All of these features in one ski provide an extremely easy and fun new ski to carve up the lake and throw a big spray. CONSTRUCTION C.A.P.T.
